LIST OF NEUROMUSCULAR CONDITIONS Muscular Dystrophy South Australia provides a range of services to people living with a variety of neuromuscular conditions. List of Neuromuscular Conditions This is a list of some of the neuromuscular conditions for which Muscular Dystrophy SA provides support, but is not a complete list. These neuromuscular conditions have certain features in common: Most are hereditary Most are progressive Each causes a characteristic selective pattern of muscle weakness There are currently no cures Each condition varies in severity but can result in significant physical disability and may reduce lifespan Page 2 List of Neuromuscular Conditions Muscular Dystrophy 1. Adrenoleukodystrophy Changes in muscle tone, especially muscle spasms and spasticity Crossed eyes (strabismus) Hearing loss Hyperactivity Worsening nervous system deterioration Coma Decreased fine motor control Paralysis Seizures Swallowing difficulties Visual impairment or blindness 2.
